Unable to install 1.2 in iPAQ 211

That's really strange. pfQuizzz should work on your WM6 device without any problem. Please try to download pfQuizzz_1_2_mob.cab once again, maybe it has been corrupted. That's the only idea that comes to my mind at this moment.

If it doesn't help, please let me know and I will provide you with a version of pfQuizzz that doesn't require installation...
